ELEVATOR.

Application filed June 6,

To all whom t may concern: f

Be it known that I, HORACE L. CAMPBELL, a citizen of the United States,-residing at the city of4 St. Louis,`infthe State of Missouri, haveinvented certain new and usefuLImprovements in Elevators, of whichtheztol-v lowing is a specification.

This invention is illustratedin the draw-V ings. in the `formA of anelevator, but thel construction is adapted for various useful pur poses,among which may be mentioned, for the purpose of examples but not forthe purpose of exhaustive enumeration, bookcases, wardrobes, grocery andother-bins, and receptacles for the storage of stocks of'mervIt chandisefor retail `and other stores. may be used, also,` for airplane bodiesfor the; reception of a load onpassengers.

The main idea ofthey invention is to provide a plurality of receptaclessuitably connected to a central shaft or rotating means in such a mannerthat the said receptacles will be maintained in a fixed relationthereto, Yand by which the contents of the said receptacles will vnot betilted or tipped or shaken orl dislodgechbut when once placed in' such areceptacle .are maintained in a stable condition on the same level.

ln the caseof elevators, the goods or articlesuare placed in thereceptacles for thepurpose of being raised or lowered from onewfloor orlevel to another. In the case ot' use vot this invention for the'storage of merchandise ory as a bookcase,the object is f to increasethefloor .space by `moving a receptacle, the contents of which is notinim-V mediatek demand, upward and `out A of` the way ywhile somev otherreceptacle is in immediate use, but with the potentiality that theremoved kreceptacle `can be easily returnedv to. a position where.A itican beI most` easily reached by the` user'.`

This device may beconstructed of any size accordingrto the purpose 'forwhich it is in- '-1 tended. It'may be comparatively small, or it may belarge enough to carry articles from floor to floor in a` tall building.

One use of this device that is especially important `is in handlingbaggage or express mattei-at a railwayl station,where, ifdesired,`:it.caribe .mounted on-wheels-or rollers and moved! adj acenty toanexpressor and elevate the s-ame to a higher runway,

platform, or floor, where it can be more easily handled than on thewalkway used by passengers and others.

ln the-accompanying drawings Jforming part of this'specification, inwhich like numbers offreference denote like parts wherever 4 they occur,

Figure 1 is an end elevationof an ernbodiment of the invention;

Figure 2 is a side elevation; and v .Figure is a fragmentary enlargedsectional-view taken on the line` 3 3 in Figure 2, lookingyin thedirection indicated by thel arrows.`

A suitable frame, preferably of angleirons orA the like, is provided,consistingiof uprights I1, cross-pieces 2, and braces 3. The frameworkshown in Figure .1 is duplicated at theother side (or end) of thestructure, as shown infFigure 2.

Braces 3 are fastened toithe housing 4, and in conjunction withbraces 17support the same at approximately the center of the framework.- Thelower braces 17 are the principal supports `for housing L1, but` areassisted in such support by the lower braces 3. The' upper braces 3 and17 act as supports andsteadying members for the housing. It is tobeunderstood that the braces and 17, as shown in Figurevhare duplicatedon. theY opposite side o1 the machine.

A plurality `ot `storage receptacles 6 is provided, the sanie-l being.adjusted to `rotate with the pair of rings 7 that, withintheabove-mentioned frame, form the end mem` bers et the mechanism.V

`Each receptacle 6 bears a ring 8 fastened thereto by screws 9 ory othersuitable means.

.Each ring 8 is `formed like an angleiron, so

y17 are attached `at one end by bolts 18 to ring 7, and at the oppositeend by bolts 19` togear 22. Bolts 2O fasten the external spur gear. 21stationary to theframe 3. There is providedxan external spur gearVZland` an internalspur gear- 1522.V Spur gear-22 is so .formed thatroller 105 l f 23 tracks "on ,onek face :thereof and roller baggage'can-and :there receive l such-matter '1 2/1 onfzanotherfface,the11eof.-Itis to bef.v understood that there is a plurality of rollers 23 and aplurality of rollers 24, the same being borne by arms 25 fixed to theside Walls of housing 4 by screws 26.

The entire mechanism .is driven from central shaft 27, which primarilyactuates gear 28, which meshes with and drives spur gear 29. lThismeshes with internal spur gear 22 and drives the same, the external spurrack 21 meshing With and driving the spur pinions 30, mounted by shafts31 on frame 32, attached by bolts 33 to braces 17. Pinions meshr with`and drive the spur gears 34, attached by bolts 35 and angleirons 36 tothc receptacles 6. Thereceptacles 6 are so attached to gears that theydo not swing thereinbut'rotate therewith. The housing /lfreniainsstationary at all times. The arrows indicate the direction of rotationoi the various parts. y

The dimensionsof gears 34 are calculated with relation to thedimensionsl of rings 7,

so that While rings 7 are revolving, the

equilibrium of the contents of receptacles 6 is maintained on an evenlevel therein because of the rotation or' gears 34. From the centraldriving pinion or gear 28 to the outward extremitresof the train ofgears, 1n-

cluding rings 7 andv gears 34, the mechanism is vplanetary in itsnature.

Rings 7 lare caused to revolve by reason of their being connected bybraces 17 to vframe 32, Which is driven by the inner spur gear 22 andgear 29.

'Braces 38 are attached. to braces 1.7, and each brace bears rollers 39and 40, which run ontraclrs 10 and 12 on gears 34. e

The rollers 23 and 24 are intended for anti-friction purposes. It istobe understood that gears 34 and gear 22 are so formed, angular incrosssection, that two tracks thereon are formed, on which theabovementioned various anti-friction rollers run.

The shaft 27 is driven by motor 41 or any other suitable source ofpower, in a small device, such as a bookcase for instance, a hand vcrankcould be attached to shaft`27.

There is a plurality of rings 7 and receptacles 6 extending from onering to the other, the Whole forming ak rotary frame. Preferably bothends of receptacles 6 are open. 1

The receptacles 6 are not mounted on shaft-s or other supporting means,but are held in position by rollers 11 and 13, and 39 and 40, whichprevent gears 34 from moving longitudinally or laterally or otherwisethan rotarily.

In the drawings I have shovvn the ring 7 driven from the inside or fromthe central receptacle but it is obvious that the source of 'power maybe located Without the rings 7 at any p'ointon its circumference butthis would necessitate a much larger gear aroundthe circumferential areaof ring 7 ,spirit of this 4invention or the means for dr than theprei-'erred form of internal spur gear 22 shown.

It should be clearly understood from the foregoing that the externalspur gear 21 is stationary With reference to the frame 3 and impartsmotion to the idler 30 only from travel of the idler 30 around externalspurgear 21.

In airplane bodies, a heavier load in one receptacle 6 Will result incausingI gequilibrium of other receptacles 6 by forcing them by gravityto equalize the Weights in all, tending to equal distribution of Weightin all parts oi the body. Ordinarily a brake will hold the receptacles 6stationary, but this brake `will be released when rising in the air. I

In case the ends ol.'A receptacles 6 are closed and a side thereof leftopen, beveled gears may besubstituted for spur gears 34 and willpreferably'be attached at the said ends.

Beveled gears may be substituted throughout for the spur gears shown inthe drawings. Y

Having thus described this invention, I hereby reserve the benet ot' allchanges in form, arrangement,order, or use of parts, as it is evidentthat many minor changes may be made therein Without departing from thescope of the following claims:

I claim: Y

l. The combination of a central driving shaft, a gear driven thereby, anidler gear7 an internal spur gear andan external spur gear, the saididler gear meshing With the said said gears, and a plurality ofreceptacles borne by the said frame.
